It's not over for the Houston Astros until Alex Bregman says it's over

The former LSU star had his major league-leading third game-winning walkoff hit of the 2018 season Wednesday. He launched a two-run homer in the bottom of the ninth to give the defending world champion Houston Astros a 7-6 win over Toronto.

On April 7 against the San Diego Padres, third baseman Bregman provided Houston with a 1-0 win when his popup dropped safely in front of home plate after San Diego four-time Gold Glove-winning first baseman Eric Hosmer overran the ball. Astros pinch-runner Derek Fisher scored from second base.

"That's one of the good things about this team, we don't take anything for granted," Bregman said following the victory. "He was busting his butt from second base. He could have easily jogged and said whatever, but that's not how we play here. We play hard and Derek did a great job."

On June 18, Bregman stroked a two-run, one-out double to help the Astros to a 5-4 win over Tampa Bay for Houston's franchise-tying 12th straight game.

"(Jose) Altuve told me that he's not bringing his bat or batting gloves to the on-deck circle, so I better get the job done,'' Bregman said after the win. "So I had to find a way."

Then on Wednesday, Bregman capped a 3-for-5 day vs. the Blue Jays that also included two doubles.

Bregman knew his game-winning bomb was gone as soon as he hit it. He previously swung at two fastballs and missed before he perfectly timed a third Ryan Tepera fastball.

"That was the first guy I've swung and missed two straight fastballs on this year I think besides (Luis) Severino," Bregman said. "So it kind of ticked me off."

In Bregman's last 12 games in which the Astros are 9-3, he has hit .353 with seven doubles, six homers and 16 RBI.

Last year, Bregman's walkoff single gave Houston a 13-12 win over the Los Angeles Dodgers in game five of the World Series.
